Campaign Watcher is an utility to keep track of coreforce development over the course of a Steel Panthers: World at War campaign.
Steel Panthers: World at War is a vastly improved version of SSI's classic Steel Panthers III, developed and made available for free by
Matrixgames.
You can learn more about the game here.

The idea is that after each battle, you use Campaign Watcher to take "snapshots" of the corresponding SPWaW save file. CW will then compare these
snapshots and compile the information into a number of tables, graphs and reports.
